According to the general arrangement of apparatus and the general scheme of operation illustrated in the accompanying drawings,'bituminous coal is carried in a boat 1 of modern construction into the slip or Waterway which extends along one of the long sides of the dock property. The coal is taken out of the hold of this ship by means of the coal-handling bridge 2, movable for apart of the length of the dock property on its own tracks and equipped with a. suitable man-trolley and an automatic grab-bucket,w hereby the coal may be raised through the hatches of. the boat and then delivered either to the storage yard of the (look, or to suitable hoppers provided for loading th'e'coa'l into cars, as hereinafter described morev at length. Simultaneouslywith the unloading of bituminous coal from the slip side of the dock, a second boat 3 may be drawn up at the channelend'ot the property and there unloaded through the agencyof an unloading tower 4, movable crosswise of the dock property and equipped with grab bucket-operated from a mantrolley and capable of delivering the coal from the boat either to the storage area of a'shed or shelter, or to a hopper from which itmay be subsequently loaded into railway cars. Each of the boats can be unloaded and its contents screened, sorted or deposited for storage, all Without interference between-the boats or their unloading mechani'sms. Simultaneously,- or subsequently, to the unloading of the boats, the coal may be loaded into railway box cars for shipment Without-complications in the switching arrangements and withoutobjectionable de lays, forthe shunting of cars.v Furthermore,

the system as a whole presents a certain flexibility or adaptability whereby the size of the anthracite shed may Joe-increased even to substantially double its initial capacity,

withoutinterfering with the generallay-out and without any alteration'in the means wherebythecoal is hoisted, transported,

graded and delivered.

a The traveling bridges, whereby. the bituominous coal is unloaded from boat 1, are d'u-,

plicats in all regards and hence-only one of them need be described-in this specification.

The bridge span is sufiicient to extend subv stantially acrossthe dock property andhas a folding apron or extension arranged'to project over the hatches of the boat. The

bridge span is supported two towers. "The supporting tower 5 on" the water side (of the steel rocker bent or sheer leg type) .is flexiblyconnected to thetbridge span in such away as to provide for minor. inequalities of gage between the ture.

tracks 6 on the rear. of'the dock and those 7 onthe front of the dock. The supporting tower 8 on the rear of the bridge is of V-leg construction and is especially designedto provide ample strength for endwise Wind loads upon the bridge and for the end thrust induced in the structure by the acceleration and retardation of the man-trolley. V The Y entire bridge structure and its two towers are flexibly related so that the span shall rest upon both the V-leg' and the, sheer leg in such a way that either end maybe advanced ahead of the other end to an angle of about six degrees on either side of a line through the center of the othersupporting tower at right angles to the rails upon which these towers travel. This is accomplished by connecting thespantoits supporting towers at their lines ofcentersby means of king-v pins, all connections being such as.to provide for rotation about these king-pins to the amount named. By this arrangement, one end of the bridge may advance or fall behind the other end Without introducing stresses detrimental to the structure. The bridge is carried on 32 rolled steel Wheels, sixteen Wheels under the sheer leg and an equal number under the V-leg. These wheels are arranged in clusters of eightunderv the four corners of the bridge and these eight Wheels are mounted in compenv sating' trucks to insure equalization of the weight brought to each, corner of the struc- The load is brought to the journals of these wheels through the agency of an equalizing plate girder 9 pin-connected to the box girder 10, which in turn is pin-connected to the supporting tower. Motors 12 are provided for propelling the' bridge along its tracks, these motors being conother or to move both ends simultaneously.

An apron 13 is hinged on the bridge structure and'is arranged to extend outover the boat for the purpose of unloading-the oal. The apron is stillened and braced against side wind, and the weight of its outer end is carried into the bridge structure through folding I-bars l l piii-conneot-' ed at their lower end to suitable yokes in the apron and at their upper end to a mast 15 built into the bridge structure. 'The constructiom of this apron and 'mast is such as to provide for the easy raising and oweringof the outer end of the-apron to allow the 013 iies sels a fir-ee Path in thesli-pa h 'ge'tljmintf of tlieapron anda e "carried to rivetedto if beamg irdersf The trolley run- .w'ay, terminates in the outer end of the apitoii land is there fp rb'vided with m ;a11tokind ca'iialile' of gree ing? applying an in- .bneket fjtlie 'clam shell variety oper- 3'0 ated 'initheiisnalinian'ner from acab :23.

The

adjacent to the end of the dock;

ings are provided to receive the man-trolley and extend from the runway level downward in a vertical line to the junction line of the I, lean-to roof, and from this pointin an inclined direction to a point ten feet above the junction of the end bulk head with the inclined roof. Shinglehatchplates or other suitable well known closures may be used to close these openings when the shed is being filled. A

suitable girder 4:9 is built into the structural framing of the shed on the end adjacent to the end of the dock'for the-purpose of carrying the end of the anthracite unloader 4.

This girder is designed not only to take the vertical loads induced in the structure by the operation of the trolley, but also to take the endwise thrusts brought about by accelerating and retarding the same. On three sides of the shed, namely, thetWo sides and 51, parallel with the slip, and the side adjacent to the end of the dock, a curtain wall 52 of reinforced concrete is installed, this wall being self-sustaining and being carried on the same footing as the steel columns which form the side framing of the building.

The bulk head on the side 53,.adjacent to the bituminous coal storage, is made of timber and is so constructed that it may be easily taken down for movingwhen the capacity of the anthracite shed is to be increased. In otherwords, it may be regarded as a temporary closure for that end of the shed.

, end of the anthraciteshed in such position A belt conveyor 5% extends along the rear that it may be usedfor carrying the anthracite coal from the man-trolley to the .loading out screening plant 55. A traveling hopper 56 is mounted abovethis belt conveyer and is movable thereover and can be placed to register with any of the various runways of the shed.

The anthracite unloading tower 4 is used for taking coal from a boat 3, lying along the channel end of the slip and delivering the same to storage area within the shed, or to the belt conveyer for loadingout directly. This loader is equipped with a man-trolley 57, operating a grab-bucket 58,. this trolley and bucket being): duplicates of those used on the bituminous coal-handling bridges. The tower structure consists of. a sheer leg. 59 extending from thedock level and pinconnected to the bridge structure which carrice the trolley. This pin connection provides for minor motions, of the face of the dock with respect to the anthracite shed, all endwise thrusts from the trolley and wind being transferred to the frame of the shed. The apron structure, which extends out over the boats. corresponds in size and type of,

construction with that used on the bituminous bridges. The sheer leg 59 of the unloading tower is'equipped with trucks 60, which may be four wheel trucks, fully compensated to equalize the load on thewheels under the top of the column.

each corner, each truck having an electric motor mounted thereon and driven thereby. The end otthe unloader, which travels on the anthracite shed, is equipped with two trucks 61, which may be two wheeLtrucks,

and in addition, suitable horizontal trucks are provided for transferring the ,endwise thrust of the structure into the framing of the anthracite shed. Even though the un-. loading tower is movable across the face of the dock and, in a certain sense,is independent of the shed structure,nevertheless that structure properly may be regarded as an integral part of the unloader, cooperating therewith in the support and travel of the man-trolley and its load of coal. It is as if a portion of the unloader were roofed over to protect the stored-coal, with the additional'feature that a tem orary end or bulk head can be remove at the back of the shed to increase the effective length ofthe storage capacityfor anthracite without otherwise influencing other features ofthe anthracite plant.

The roof of the anthracite'shed is carried on vertical columns 'or steel structures and each of these columns carries at its top and separate from the; roof, a runway for the man-trolley of the bridge, this runway being suspended from a cantalivencarried at In the structure shown in Fig. 5, each runway comprises two I-beams each secured at the lower end of a diagonal member 63 which depends from the horizontal girder 64-, the latter being arranged and braced as shown in the drawing. Fig.7? shows a modified type of cantaliver suspension wherein the runway'consists of but a single rail 65. With a monorail runway as above described, the man-trolley is slung in a suitable hanger which need not here be described,

In this specification the means -for transporting the grab-bucket has been referred tov With this arrangement, the bridges can re- I ceive current from one pair of feeders on one side of the line of posts and the box car loaders and bituminous screemng plant inay take current from the other side of the line of posts. This arrangement gives a com-- pact electrical system, while at the same-- time insuring extreme flexibility in the manipulation of either. the bituminous bridge or the screening plant, or the box car loader. a

Although I have above described a complete plant embodying the novel features of 3 my present invention, 1 have not deemed it necessary, to an understanding ofthe features herein claimed, that all details of the .systein should be shown in the drawing, or

mentioned in the description. These details 1 are built in accordance With approved engineering practice and may be varied in many Ways without changing, in a radical comprising,

bridge, coil-hoisting means carried by sald budge and lncluding a grab bucket trolley,

.Way,'the basic and \underlying principles of the complete system or structure.
